similar to: RC2 better than RC3? Graphed!

I have run an ogg analisis using EAQUAL from -q 0 till -q 10 evaluating bitrate and quality. The results are shown in a nice graph, and can be seen here: http://audio.sinderman.com/ One thing I have found is a bug, as it is cleary shown by the blue lines. Other discoveries are written in that page, and others are still evolving in my mind :) The goals of this analisis is to help the developers

This is the new page after the first feedback round: http://audio.sinderman.com/ Comments? Conclusions? Developers feedback? Can someone ABX 60.wav with 60.ogg -q 0? Cheers, AGS. P.S. Garf/Erik, I have included some comments from EAQUAL's author. <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this

I am but a poor code & compile illiterate, making it impossible for me to create Windows binaries from the EAQUAL source (http://sourceforge.net/projects/eaqual/). Would someone be interested in providing said binaries? They would be very helpful to me in evaluating Ogg Vorbis and other audio codecs. I'm also sure that other people would benefit from the program. -- GMX - Die

For those who are interested, I've run 3 EAQUAL tests on both the LAME and OGG encoders: LAME with the --alt-standard preset (with and without --nspsytune) and OGGENC (RC3) with -q 6 (my personal "sweet spot") I am somewhat unsure though about the validity of these tests, since the original and decoded files were not the same size (2 KB difference). The LAME encoded files were also

Hello: Does anyone know if Garf's tunings have been integrated into CVS yet? I am waiting for that before upgrading.

Hello, I'm seeking advice here as I'm intend in the not to distant future to start encoding my CD collection, and I'm not sure what to use. Do I use the still current v1.0, or am I better off using a newer build? Also, I've started to notice mention of versions 1.0.1 and 1.1 in these mailing lists. Are these worth holding out for? I'll probably encode at about Q7, and am using

http://audio.ciara.us/test/index.html http://audio.ciara.us/test/128extension/results.html AAC, MPC, Vorbis, WMA 9/Pro, Lame & Blade were tested at 128k vbr. MP3Pro, AAC-Pro/Plus(?) and older versions of WMA were not tested. Looks like Vorbis tied with AAC, MPC and WMA 9/Pro for first. Although it was a four way tie, Vorbis was on the low end. And LAME was only slightly lower, comming in

Hi. I think that the vorbis team should use this version of OggDrop RC3 as the official OggDrop RC3, because the menu interface is easier to use (& you can see what kind of mode you have chosen). http://www.inf.ufpr.br/~rja00/BQoggdropC1.zip See this thread for more info: http://www.hydrogenaudio.org/forums/showthread.php?s=&postid=4683 <p>I only have one problem now: what

Hi, I just built a sample application with speex resampler in linux and I tried to resample 8K sine wave tone mono to 48k using speex_resample_process_int. I am using a tool called EAQUAL for audio quality. I find the quality of Speex resampler to be decreasing when I increase the quality q of the resampler init function. Can some one give me pointers regarding this?? As per the API, if the

Hello All, I have a device that spews out experimental data as a series of text files each of which contains one column with several rows of numeric data. My problem is that for each trial it gives me one text file (and I run between 30 to 50 trials at a time) and I would ideally like to merge all these text files into one large data frame with each column representing a single trial. It is not

Hi folks, We're gearing up to the next full release of the Vorbis codec; I've just tagged a release candidate in SVN in order to encourage wider testing toward final 1.1 release. This release includes the following updates: 1) Adoption of AoTuV and other tuning work by Vorbis developers outside of Xiph into the mainline codebase 2) New bitrate management code 3) bugfixes In more

Hi (hope I am in the right mailing list!) I really can't figure out how to use Vorbisgain in OggdropXPd - it doesn't seem to work so far. Can Someone pls. explain detailed (steps) what to do when using Vorbisgain in OggdropXPd? I understand the settings for Vorbisgain are in "decoding options"... why? What I really want is the function of Mp3Gain on Ogg-files, and I thought

hello celt developers. im just wondering if its possible to compile celt codec for windows? if so, could someone point me in the right direction? thanks.

Hi, In paper" A High-Quality Speech and Audio Codec With Less Than 10 ms Delay", you are mention that: There are still several ways to improve CELT, such as by incorporating better psychoacoustic masking in the dynamic bit allocation. This is a difficult problem both because there are few bits available for coding the allocation and because the analysis window is short. it is

Dear all, I hope to remove a whole column from a data frame or matrix (> 2000 columns). All value in the column are same. The first thing is to select those columns. For instance, I hope to remove the V3~6 column, for all the value in those colume is zero. V3 V4 V5 V6 V7 V8 V9 V10 1 0 0 0 0 0.000 0.000 0.000 0.000 2 0 0 0 0 0.000 0.000 0.000 0.000 3 0 0 0

Hello all I have been encoding to OGG as a default for well over a year, but I recently thought I ought to test how it sounds compared to other codecs. I got the Windows Media 9 encoder and I was quite surprised at how bad a job OGG did at quality 0 with a simple piano clip, and how well WMA9 was - I've always considered WMA as being a bit naff, but WMA9 has forced me to re-access this view

Dropping the other topic as requested, I'd like to follow something up in a new thread. I want to throw a question or two out there and see what responses people give (if any ;-). Assuming that you think Vorbis could have developed faster than it has done in the past year, what in your opinion has been holding it back and what remedies do you suggest? Speaking for myself, I think that it

R-users, I have the following piece of code which I am trying to run on a dataframe (aga2) with about a half million records.  While the code works, it is extremely slow.  I've read some of the help archives indicating that I should allocate space to the p1 and ags1 vectors, which I have done, but this doesn't seem to improve speed much.  Would anyone be able to provide me with advice on
